Which of the following best compares how environmental conditions in Brazilian coffee plantations and American tobacco plantations contributed to migration patterns? Brazilian and American plantations in tropical regions discouraged the growth of food crops and limited the numbers of laborers who migrated there.
Both regions required the importation of immense numbers of laborers to produce in-demand cash crops that could only be grown in warm-weather climates.
Depleted soil conditions caused both regions to shift from cash-crop production to subsistence agriculture, decreasing the number of workers moving to the respective areas.
Laborers from outside the respective areas were encouraged to immigrate to help produce additional food crops in hopes of maximizing economic production prior to colonizing new territories with richer soil.
